In my neighborhood as well as within my own home there are several WIFI routers I can connect to. Many times the iphone will not automatically switch to the network with the strongest signal and I need to go into settings>WIFI to manually choose the network I want. Are there any jailbroken tweaks that can help me with this? I was thinking either something that automatically connects to the best WIFI network (better than what's built in to 4.2.1 already) or a quick switcher of some sort. On a related note... I've always thought the iphone (3g, 3Gs, and 4) has always been bad at properly leaving WIFI networks. I usually have to go to SBSettings and turn off WIFI when I'm clearly out of WIFI range, but it gets stuck on a network I'm moving away from. Anyone else have that problem?
