I have a couple of questions before I update to the new OS. After updating the OS to .147 my network connections started to have problems. First off all my "blackberry internet service" did not connect anymore and sometimes my 3G and EDGE connections dissapear completely and I cannot receive emails or IM. Im using a SIM-free phone on an O2 network in the UK. Is this purely a network problem or is it related to the upgrade to a beta OS?
