My mobile AP works!

I would like to help and give my solution, but not enough to go out of my way to register in a forum, so I'll be lazy and post on blogger and hope Google points stranded folk here!

To use the internet on my tablet (Samsung Galaxy Tab 2) I need to tether my phone (Samsung Galaxy mini) to it sharing the internet via WiFi. I am not with AT&T (which blocks tethering). In other phones "mobile AP" works a treat —in Gingerbread (Android 2.3) the option is in the silly bar that one has to drag down quickly like rolling blinds with a level of coordination beyond me.
In my phone which runs Froyo (2.2), it does not work: it connects, but no internet.
There are forums discussing this problem without avail. I stopped short of rooting my phone or updating to gingerbread.
I stopped because I got it to work. I remembered that the native internet browser did not work, hence my use of opera for browsing, so I googled that problem and the solution was simple: delete the APN of the mobile carrier and type it in manually. I did it and my browser works —but opera doesn't— and surprisingly so does my mobile AP.

Now my tablet can suck up all my data allowance via WiFi… as if its cost was not a problem enough.
