I'm currently wondering whether I should get an iPhone 4s or not. I currently have an iPod touch 4g, and a cheap Metro PCS qwerty keyboard. Is there any way I can transfer my number from metro over to Straight Talk? Plan on buying the phone unlocked from ebay or craigslist for about $200, as AT&T's plan is too expensive for me. I also plan on using straight talk on it, so I will be paying around $45 a month. Also, since Straight Talk only works on GSM phones, will I have to buy a specific carrier model such as AT&T? Or can I just get a verizon/sprint model and still use the straight talk service? I'm really confused about that. So my question is, would it be worth it? I'm not really interested in the iPhone 5 at all.
