I recently discovered that the Twitter application Seesmic had been ported onto the BlackBerry and was available via the App World.
Unfortunately after downloading and installing, I encountered a problem which meant it could not connect and fetch any updates.
After a few Google searches I eventually found that entering the APN details for o2 would solve this problem, so headed over to Options – Advanced Options – TCP and entered the following details:
Username for APN: o2wap
Password for APN: password
Upon returning to Seesmic I was glad to see that the application was now functioning as expected.
It wasn’t until about an hour later however, that I discovered my web browser and google maps applications (amongst others) were no longer working.
After a bit of trial and error I found that changing the default browser configuration (Options – Advanced Options – Browser) from Internet Browser to O2 Active soon solved the problem.
