Blackberry 8530 is not working in Sao Paulo, Brazil... can't call out, no incoming calls/texts, data plan working... can someone please help? Frustrating, because before I left on this trip, I specifically upgraded phone to what Verizon said I needed to be able to use phone and have internet access on my phone (Blackberry + international data plan)... and nothing is working. I emailed tech support 2 days ago, and no response. Any advice is much appreciated! Will send cookies when I get back to states. :-) Will be here 8 more days... really need phone. Thanks in advance!
