I'm pretty sorry for making this thread, I'm sure this community has seen it's fair share of phone carrier questions. Putting that disclaimer aside, I have questions about using an iPhone on T-Mobile. 1. iPhone 3G can be unlocked and used on T-Mobile correct? 2. There is no MMS support for all iphones correct? 3. I have unlimited texting/MMS, but no data plan. Is a data plan needed to own an iPhone on T-Mobile? If not, will an iPhone send inadvertent fees? Again sorry for posting this question. I'm in the market for a refurb. iPhone so I'm asking.
