A buddy was telling me that his I2 got it's update to GB 2 or so weeks ago and since then the signal strength has really sucked. He says that before the update, it was great, but after, pitifull. Is this a known issue or any work arounds? I had him pull the battery just in case and restart but it didn't halp at all. I'm showing 3 bars with my Charge and he has 0 bars.
