RichieBoy, I am experiencing the same crashing trouble. I have no fix for you, but the iHub app on my iPhone 4, (running mostly on my home wireless network), crashes at different times. Sometimes when typing a longer post, many times when going to a member's posting history.
I have tried closing all open apps except iHub, rebooting the phone, all to no avail.
I also have problems when replying to posts in a thread, the message fails to go to the member listed at the top of the typing page, but it ends up going to the next to last message viewed before the reply. That is annoying, not only to me, but to the errant member who received it.
Hope they fix these bugs.
Hang in there, it will get better.
