Hey I have the BB 8520 and my sister has the 9700 bold the reception in our home is horrible so we both connect our phones to wifi and with the wireless internet in our house it gives us stronger signal and it says UMA. But recently when she connects and it works then my phone gos to sos. But when I take the battery out to reset my signal it works then her phone messes up so what I'm tryin to say is she gets reception I don't? I get reception she don't? Confusing can anyone help thanks god bless.
