First off - I have searched (this site and a few others) but I think the terminology might be too generic and I'm not getting the exact answers I'm looking for; just bits and pieces and it sometimes conflicts itself - so I do apologize in advance if this has been covered elsewhere. Anyway - How do the Pay As You Go plans work for AT&T and/or T-Mobile in the US? Is there a benefit to choosing one over the other with an iPhone. (I'm obviously assuming the pre-requisite hack/jailbreak has taken place and the iPhone is able to work with a Pay As You Go plan.) I currently have Verizon for my cell contract and have no intention of leaving or giving up my phone with them, so if I got an iPhone I'd only need data. I'd rather not pay $70.00 a month for that (The base fee and all taxes, etc) - so I'm hoping its possible to use a Pay As I Go plan and save some cash each month. I currently have a jailbroken IPT and love it, but there are times it stinks to not have a data connection (like on my train to work everyday!) So, without getting too wordy (if its not too late ) - what are my best options - if any - to get inexpensive data on an iPhone? Thanks in advance!
