If you are looking to disable the WAP then here you go:
This is a guide for those of you thinking of getting the iPhone but dont want to pay for the ridiculous data plan or already have the iPhone and want to get rid of the data plan. *
For those of you that didnt know, the AT&T forces iPhone customers to get a data plan when they purchase the iPhone 3G.* The data plan is $30 dollars a month without any text messages. *
I had the previous iPhone and now have the 3G iPhone and both times was successfully able to get rid of the data plan without any problems.* If you call AT&T to get rid of it theyll say no, but there is a way to slightly manipulate the situation to get rid of the plan:
1. *Get an old phone compatible with AT&T or Cingular.* You should have one considering you just got an iPhone or planning to get one.* If you dont have an AT&T phone, just call your previous service provider to unlock your previous phone, takes a few minutes
2. After purchasing the iPhone and its service plan, call AT&T customer service, or you can chat with them through their website.
3. Tell them you just got iPhone but youre thinking of returning the phone but want to keep the voice plan since youll be using a different phone (youre allowed to return the phone but keep the service).* Make sure to tell them to get rid of the data since youre no longer using an iPhone.
4. If youve already had the iPhone for a few months then just tell them youre no longer planning to use it so you dont need the data plan but would like to keep the service on a basic service.
5. The rep will ask you for the serial number of your other phone.* Give them that.
6. Theyll then ask you to take the SIM card out of the iPhone and put it into the other phone.
7. Once you see service is working, ask them to block out the Internet service (WAP) completely.* This will come in handy later. *
8. After youre done hang up and switch the SIM card back to the iPhone.
9. On the top right hand corner you should no longer see the 3G data sign, which means you no longer have data service. *
10. The reason for asking to completely block out Internet service (WAP) is so that if you accidentally hit the Safari browser you dont get charged per kilobyte, which can get expensive.
11. Now with wi-fi you can access the Internet.* There are some people who believe you get charged for using wi-fi, YOU DONT.* If the wi-fi is free, ATT cannot charge you for that.
