To be honest it's not so much the tethering that bothers me as I rarely need to reboot phone. Although some few cydia tweaks do require a reboot on install. Also my phone has occasionally randomly rebooted itself. I pick it up and the greenpoison skull is looking at me! So that would be annoying, but I guess that might not haoppen with a new jailbreak. I think I have too many tweaks running and there's a clash somewhere. I think I'm just gonna cautiously wait and see until there are more options available. As I say there isn't much that tempts me on ios5. I'm never gonna use Siri, and biteSMS is a great messaging app. Icloud doesn't appeal that much to me, and lockinfo gives me all the notifications I need. Maybe I'll change my mind when I see it; I have only had a quick look at a workmates phone running ios5
