Hi Guys,I am planning to visit India in couple of months and planning to get a SIM with BlackBerry services for my BlackBerry BOLD 9900(850/1900/2100 MHz) model.So, I have follwing questions:1. Would I have to reconfigure all email accounts on my phone with new provider?2. I have heard all operators use 2100 MHz for 3G is it true?3. What would be my best bet when choosing provider, in terms of coverage, 3G speeds, reliablity etc?4. Will all operators support tethering?I would greatly appreciate if you could shed some light on above.Regards
