So I've got a factory unlocked iPhone 3GS, activated it with an AT&T SIM card, then slipped in my T-Mobile SIM card and used it merrily for a month. Not being being able to leave well enough alone, I decided to get a different T-Mobile SIM card, this one with unlimited texting and web, and 100 minutes of talk time for $30 a month. That one is a "new" customers only prepaid plan, hence the new SIM as opposed to just changing the plan.
Activated the new SIM, inserted it into aforementioned iPhone, and ta da! No service! Meh, let's just put the other one back in. Yay! Also no service. WTF?
So, how do I fix this?
