Trapster is a website that uses Google Maps to show you where police speed traps are located. Combine this with a GPS-enabled cell phone and you can get a warning whenever you are approaching a “speed trap”. Users of the website can mark new speed traps they encounter to warn other users of the site. Here is a video demo of Trapster in action:
Before you can perform most of the “hacks” for the Samsung Blackjack SGH-i607 cell phone you need to “app unlock” it. This process unlocks the phone such that you can alter the factory settings and software that comes preconfigured on the phone. Here is how to do it:
This is for the AT&T/Cingular Nokia 6030b type RM-75. If you get the newer RM-225 model you CANNOT unlock it through the site listed below. The model type is on the sticker behind the battery near the IMEI code.
Select phone model 6030B and select “U.S.A.–CINGULAR – Pacific Bell Wireless” as the carrier.
You will need the 15-digit IMEI number from the phone. It’s on the sticker under the battery, and you can also get it by entering *#06# on the phone. (Both of these should give you the same number! Enter the number on the form also, and click “Get my codes!”.
Remove the SIM from the phone (it’s under the battery), replace the battery, and power the phone back up. It will say “Insert SmartChip”.
Follow the instructions from the web page to enter the code. You should get a message “Phone restriction off” which means the phone has been unlocked.
You can now put your AT&T SIM (or any other SIM) back in the phone. If the code doesn’t work, do not keep trying. After 5 attempts your phone will be permanently locked to AT&T/Cingular.
Looks like those leaked slides on the Internet were right. AT&T has changed their data plans. They appear to have totally separated Text messaging from the PDA data plans. The data-only PDA plans are cheaper now but when you go to add a Text messaging package you end up paying more in the end. In my case, the PDA Personal Max plan which includes 1500 text messages for $39 would now cost $50 per month ($35 for the PDA data plan + $15 for the 1500 text messages option). I am pretty sure they are grandfathering in people who had the previous cheaper package.
My online account manager still shows me as having the PDA data plan “PDAPERUNL1500MSG” for $39.99. It looks like AT&T hasn’t gotten around to changing the PDA data options in the Online Account Management website so if you were thinking about getting one of those plans you better do it now before the website is changed to reflect the newer rates!
