well I am not sure having keys or not is really the issue. Even if the iPhone had keys the text of forum posts would be too small to read without zooming in and then you would have to keep adjusting the view to continue to read what did not fit on the page. The forum app re formats the post to fit the screen width with letters that are large enough to read without zooming... really that is all it does.... (its like turning on word wrap in "notepad")
For posting it seems to use the messages app format. simple clean, no emoticons etc... 14toeside will be disappointed...
Really? I just flip my iphone 4s sideways into landscape mode and don't need to zoom in at all.
I tried the app out, it is ok I guess. I'm just used to reading full websites on my phone, and found the app kind of limiting. I don't have any issues with the text size or typing into the text boxes, most of the time I reply it is from my phone (while I'm at work
If you update the forum software (as in phpBB) there are a bunch that include mobile versions built in and also work with apps that already exist for all smartphones.
