Thanks, iCrank and Unleashed,
I know my hardware will support the OS, my question is will the OS support the local service capabilities. I have a Wilson signal booster, if that's what you're talking about, and unfortunately you can't get cheese from a turnip. The nearest 3G signal is 25 miles away, and the signal booster can only boost what's there.
Some of the mifi devices can do 3G & 4G, but not apparently EDGE (based upon personal experience), hence my question. I don't want to upgrade to unusable equipment or OS... I can't find any information on the subject.
Thanks again,
