I have three cellphones and no home phone. I have 3GS that that's stock, fast, and reliable. I have a 3G that jailbroken and unlocked with T-Mobile (prepaid acct- no monthly fee or data), so I can get my fix with customization and JB apps as well as have a phone that's ready to go for use with Prepaid SIM's all around the would for future traveling. I have a so far indestructible flip phone with Sprint, and only use it when I'm rollerblading etc so I don't have to risk breaking an iPhone. I forward my calls to the other (could also use GV) when not using the primary line. I'm only paying $105 after taxes for all three with my work discounts with Sprint and AT&T, so it's not like I'm wasting a lot of money to have three.
