Hello. I am currently wondering whether I should get an iPhone 4 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. So my question is, would it be worth it? I'm not really interested in the iPhone 5 or 4S at all.
