well i'm pretty sure that cell phones use some sort of flash ROM. i have a data kit able to read phone data and i'm sure it could be used to mess with the OS. thats the only thing i can think of...
i checked with my provider on the roaming and they said they have contracts with the owner of every tower up here. we're no where near a freeway or any other thing ppl would care about; the only thing we have is a walmart...perfect signal in there *cries*. i have a car antenna (a full cradle kit that connects to an external antenna).
i'll be driving along and the phone will switch to another tower and sometimes it kicks me out of digital mode (no phone option for digital only) and analog works well in my area that if its the only signal u can get in the area, u might as well back over your phone. thats why i was wondering about OS replacement or some sort of App i could download.
like i said before, i've both seen and heard of people who are able to do a ton of cool stuff with their phones from picking (and locking onto) specific towers, changing what shows up on the caller ID, picking service company (version towers, Alltel towers, etc) and a bunch more. this guy could do ANYTHING he wanted to.
sounded like i was SOL from what u said b4 but hey anything u or any1 else can think of to help would be wonderful.
