Hi all, my first post!
I'm gonna give this a try as well - I'm also on Altel. I can't say I've noticed missed calls/msgs or had problems, but I do notice low signal strength (0 - 2 bars) quite often. It's really been bothering me! Not to mention very rapid battery drain... I doubt I talk more than 5-10 minutes a day, with some texting and maybe a few quick jumps on Facebook - and by late afternoon I'm usually down to 25%.
I'll update this once I've given it a fair shake. By the way, to the OP - are you still using the stock Alltel radio? Sorry if I missed that in the thread. I'm using the VZW 1.03. and Mighty 4.5.
Big thanks to everyone in this forum for being such a great resource!
