I'm currently on Cricket with a cheap phone and the daily plan. I was just given a Gravity3 that's not connected. I'm a moderate phone user, but I'd use the web a lot if I had a phone that gets it.
What do I need to do exactly to hook-up the Gravity3? I understand I need a Sim card, and I saw one place giving it with an account. I've prefer not to make a long term commitment. What is the procedure and which plan should I get? Do I have to pass a credit check? Should I get the sim card via eBay rather than from T-Mobile?
