Gps Cell Phones
By Anne King, Sat Dec 10th
Motivated by the events of 9/11 2001 and problems with 911 callsfrom cellular phones, the FCC requires that by the end of 2005all carriers must be able to trace the location ofcell phone calls to within a range of no more than 100 meters. Cell phones are already available with GPS technology installed.These systems are not the same as the GPS devices used byhikers, mariners and drivers. Lower cost models do not allow theuser to enter data such as mapping software. All systems requirea wireless network. Cell phones with GPS technology use AGPS (Assisted GlobalPositioning System). Assisted because the system uses both cellphone towers and satellites as location finders.
There are advantages and disadvantages in the new technology.The cost to implement the program will be passed on to consumers-– cell phones will cost more. Privacy is a real concern withthe general public especially in this day of identity theft. Itis a concern that unknown people will be able to access yourlocation. Also there is a possibility that the spam you areflooded with on your home computer will now be sent to your cellphone. Using GPS cell phones to track people has some great advantages.Locating kids and family can be a blessing. Remember though, ifyou try to locate someone who is out of your calling area, youwill be charged extra. The obvious benefit for the consumer is the issue of emergencyaid and that was the catalyst for this whole idea of GPS cellphones. A 911 call that
My mail provider (fastmail.fm) allows each user to create unlimited addresses. For example, when I register with Amazon I use "amazon@myaccountname.com", this site might get "lifehacker@myaccountname.com", etc. If I ever were to start getting spam to that address, I can easily shut that particular address off. (Plus I get the satisfaction of knowing who sold my address.
I end up with about 1 or 2 spam messages per week that get through the filters, and very few false positives. From my phone I can retrieve messages with IMAP or POP.

I use Gmail as a Spam Filtering service also.
For example:
PUBLIC@EMAIL is my spam pron public email address. I forward emails that come to that address to my private Gmail account and then use a Gmail filter to forward all the emails it receives (minus the spam)to PRIVATE@EMAIL, my private IMAP address. This is what my treo connects to. The "reply-to" field in my IMAP settings is always set to PUBLIC@EMAIL so no one ever sees the PRIVATE@EMAIL email address.
It's working great, and best of all it's free. shalosophy ]]>
I wrote my own anti-spam solution for my Blackberry. Using my "sent mail" mbox file on my server I generate a list of any email address I that I have ever sent to or mentioned in an email. To make sure I am always updating this list the Blackberry sends a "BCC" to my server where the list is kept.
When a new message comes in it first hits my server, it checks this master list, then saves a copy to the HD and forwards another to my Blackberry account. This means I can avoid using the "pop3" access which is only updated every 15 minutes. Using the BB address I get the message almost instantly.
I've been using this system for a little over a month now, it has room for improvement but it's easy to use. New contacts? Just send them a note first, or troll your spam folder. ryanweal ]]>

My solution is to forward all email to my free Gmail account and then use the POP functionality to access my email on my Treo. There are limitations to this (must be able to forward email and Gmail's POP is a bit dodgy), but it is free and Gmail catches 99.5 percent of spam for me.

I have a gmail account. I have never given out the email address to anyone (apart from a couple of people who I sent gmail invites to). Everyone uses an email address at a domain name I own, which forwards to my real email address and gmail claims all email was sent from an address at my domain name. My website only has a contact form, not an email address, so as to hide my address.
Yet still I get 5 or 6 spam emails a day sent directly to my gmail account (which gmail always correctly identifies as spam). I find this very annoying as the only step I can think of to make my email any more spam free is to not have an email address at all. davosmith ]]>
I have been using SpamBully, a desktop spam filter to do this for a while now. It has an option to just forward any good email that pass through its filter to another email address (cellphone email address). Only thing is you need to leave your mail client open and computer on. Not a problem for me, but may be for some. delay ]]>
I also use Gmail to filter my spam. I receive a really big mountain of spam everyday. Gmail stops about 500 spams/day and pass 200 e-mails. From this 200 that pass, about 100 are spams.
All my work accounts are forwarded to my Gmail account. There, after spamfilter, it redirects everything to a special IMAP account.
I like the IMAP server a lot. Use it to have my work computer, notebook and Treo all sincronised. fperuzzo ]]>
Please don't recommend Challenge/Response spam filtering!
Spammers don't use real "from" addresses. In fact, they usually use someone else's address, rather than just making one up. (It makes it more likely for their spam to get through.)
So if a spammer sends out a ton of e-mail from an address or domain that I own, all those automatic responses from people using C/R filtering will come to *my* inbox, even though I had nothing to do with the spam!
I get tons of spam anyway, and these "Are you a human?" messages are really annoying.
Instead why not just use Gmail, or someone like Fastmail.fm, who do "normal" spam filtering on the server, instead?
If you use Challenge/Response filtering, you are causing a bigger problem than you are solving. Lion ]]>
Spam was getting to be a problem on my mobile device... but then, it was getting to be a problem everywhere. But if you're like me, you have to use the company's e-mail, so big brother can watch what's happening. And big brother's spam filters are weak, weak, weak.
To aggressively tackle the spam problem, I set up a new Gmail account, then forwarded my work address to it. I use Thunderbird to access the Gmail account, then apply a filter to bring the contents of the Gmail inbox back to my work IMAP account. I keep Thunderbird running at home to do the filtering for me, so the flow of e-mail is pretty steady; I doubt if anyone even notices that Gmail has first crack at everything. And since my mobile connects with my office server, the spam problems are all but solved. RossWhite ]]>
Hm, guess my comment didn't appear.
@DramaQueen- if you login to sprint.com, there's a section that says Text messages ~ preferences under my content manager. Something like that. You can block select senders of messages, or allow only those in your preferred list of friends. Good feature. katana ]]>
DramaQueen-- if you login to sprint.com, click my content manager, then text messaging and preferances-- there's a way you can block certain texts.
You can even block all but a specified list. It might very on how to get to that screen since you have nextel, but they have pretty good options. katana ]]>
You have some really good ideas here, but my question is...
How do you stop the spam TEXT messages??? I actually had to have Nextel turn off my internet on the phone because it was getting so bad...and I protect my cell number like it's my last bit of oxygen! LOL! Obviously, either one spammer got it and sold my number or it was a random dial thing.
Now, it wasn't a huge deal to turn off the internet because I don't "generally" text or email from my phone, but I would like to occasionally download a ringtone, which can't be done with the service turned off.
Any ideas for this...anyone? Drama Queen ]]>
Oh, I see your story does say "personal e-mail." Heh, you were ahead of me. ;)
Too bad a lot of my personal e-mail still comes to my work income-- actually, my work e-mail is forwarding to my personal e-mail (quota issues), but I still receive some e-mail from friends in my work address. katana ]]>
I like the idea. However, SpamArrest for work e-mail doesn't seem like a good idea IMO. Like others, I hate-- and often refuse to-- respond to people's "are you human" authentication methods. For personal e-mail, sounds good. katana ]]>
can be quickly located, emergencyroadside assistance, locating persons missing in remote areas,the list goes on. If coverage is available then GPS cell phonessave lives. Many carriers already have GPS cell phones available. You canbuy the basic model for emergency tracking or you can pay forthe technology that turns the into a sophisticatedmapping, PDA system. Problems are still an issue with theadvanced features. The more you use the advanced features, thegreater the drain on the battery. Increasing battery size alsoincreases the size and that is a problem for mostconsumers who want ever smaller, lighter devices to carryaround. At this time Japan seems to have the edge on developingthe high-end miniature GPS cell phone. Sacrificing privacy for safety is the issue and I suspect thatit would only take one positive outcome in an emergencysituation to make the decision for you. As the systems become more and more refined camera and PDAcapabilities are being included into the phone itself.Developments in GPS technology are continuing. Ifprogrammers can solve the issues of privacy then the potentialfor GPS cell phones is incredible. It will no longer be an issueof "Can you hear me now?" Rather the question will be, "Can youfind me now?"
