Personal hotspot falls asleep...

Hello everyone!

I've searched the discussions but can't seem to fnd this issue (maybe it's my wording??) and I know I can't be the only one experiencing this issue. Check it out, this is whats happening...

I recently bought an iPad 2 wifi (LOVE IT), opting not to pay extra for 3G since my iPhone 4 has a personal hotspot built in. And this was a good idea I think, but I'm having what I believe to be an odd issue. Maybe it's normal but knowing Apple like I do I doubt this is a feature :) Anyway I enabled the hotspot on my iPhone and looked at iPad network connections. There it was ready to connect! That worked great. The problem, though, is that it drops after not being used for a while and the only way to reconnect it is to go to the iPhone Settins > Personal Hotspot and turn that feature off and on again.

This is kind of annoying because I would have thought that once it's enbled, any time I wake my iPad up it would reconnect to the iPhone if it's in range of the iPad. Am I just wishful thinking or do I have to go into the iPhone and iPad settings every single time I want to use the hotspot feature. You'd think it would attempt to work similarly to how my MacBok Pro and iPhone get along. The difference being it's using USB I suppose. Every time the two connect, the hotspot kicks in and I can hop on the Internet from the laptop.

Am I just wishful thinking or is this how everyone does it... dodging the Hotspot Settings Shuffle ;)

Thanks in advance for your thoughts on this!!
