Motorola V3 Force ARFCN

Hello, While experimenting with a Motorola V3 GSM branded for AT&T, I enabled the Engineering Menu with a SEEM edit. Not a terribly hard procedure once you know where to look. After performing this hack, I looked in the Engineering Menu, and there is an option to force the ARFCN the phone camps on. I think this would be a useful tool if you want to force a handset to camp on your Base Station. I'm not if it will help with the clock issues, but it might alleviate some frustration. The Original V3's (no 3G) can be found on ebay for a decent price. I'm not sure if any other phones include this functionality (I haven't come across any), so I thought I would share it with you all. If you need help performing the SEEM edit, let me know. Caleb
