I've just tested the forum editor on the ipad and iphone with IOS 5.0.1 and it works fine on both. This is not so much a forum issue as it is an issue with the safari browser. So for all those that have mentioned this to me, the solution is to update your device to IOS 5.0.1
With apologies for being so non-technical, on iPad2 I can't respond to threads because the on-screen keyboard doesn't appear. Are we saying that downloading the latest IOS (5.0.1) will fix this? Or is there another trick to it since some people appear not to be having the problem?
Another fan of Firefox on Mac and Web Browser on IPad
