cell out

so i'm thinking that getting a mobile phone would be a good idea. any suggestions? i'm a little conflicted over getting just a bare-bones phone and one with nifty features (bluetooth, camera, whatever), although i suspect a bare-bones phone would probably be the best bet for me. i'm sure the service level that will make the most sense is one level above for-911-only. the basic t-mobile national plan and the sony ericsson t68i seem like a safe bet. $20/month for 60 any-time minutes and 500 weekend minutes, $35 activation, and the phone is free.
