infact you don;t even need a data plan on your iphone to get internet through your carrier.

you can use public proxy’s in place of your carriers data connection to receive free internet.

beware though, most carriers monitor bandwidth on all accounts and you may receive a phone call regarding your usage.

the best answer is, ” my phone has been acting really weird lately and the battery seems to die every 45 minutes.”

this will elude the accusation that you are actually stealing bandwidth because your phone appears to be malfunctioning and the probability that it is using the networks resources as much as it is using your batteries resource would limit the finger pointing to your phone.

generally you wont get caught or noticed unless you are tethering which will use LOADS of bandwidth.

there is a much easier way of doing this.

on t-mobiles website, there are detailed instructions on how to set up your iphone for use on their data network. you can even get mms to work on 3g iphones.

its very simple and takes no brain power. if you are confused, t-mobile actually will let you speak will tier 3 tech support to have them guide you through.

the only thing is the 3g speeds are actually edge speeds which are generally around 110/kbps.
