New iPhone software upgrade 2.2 will be rolled out as soon as it becomes stable. In this upgrade
1. Push e-mail to iPhone or iPod touch will be restored.
2. This upgrade will also improve on GPS functionalities.
3. We’ll see new Safari browser having search beside the address bar and it will be always visible.
I wish that we can have Copy and Paste functionality in coming upgrades. I don’t think this is difficult to implement, but still we haven’t have this important feature in it.

There will be some existing bug fixes. I don’t have exact detail as of now. I’ll write it here again as soon as I get some thing new.
