Automatic wifi/3g sharing!!!
I experienced something I found to be quite interesting before upgrading recently to 3.1. I was previously running 2.2 or 2.2.1 jailbroken--don't remember which--and my iphone automatically shared its data connection with my laptop over my laptops adhoc network. I know of programs like pdanet--which I had installed at the time, but I thought you had to have it opened and running in order to piggyback off of the iphones data connection over wifi. This was not the case for me. I could turn off my phone, turn it back on, connect to the laptop over wifi and *BAM, i was in business--never had to open pdanet though i may have once before i realized i could do this. it was quite handy and was just wondering if anybody else had experienced or heard of this phenomenon before--or if it is even normal...perhaps even how to replicate it???
