Mathieu C.'s wonderful ideas emporium!
Following up on the 2G-only bug

First thing in the morning I try my application to see if the bug is really fixed and it doesn’t work anymore!!! I was a bit sceptic about yesterday’s solution and it now confirms my doubts. One more thing I tried now is switching the APN to internet.com versus rogers-core-appl1.apn which is supposed to be an Android-optimized APN and now it works again… Strange. I shall report that problem to my technical contact @Rogers.
