I'm not sure if there is still a good enough reason to jailbreak except to get those eye candy homescreens and notifications, which I'm not really fond of. These probably would drain the battery anyway. Multitasking for the official firmaware (since 4.2?), though limited is fine for me. One of my wishlist I suppose is to get that mirroring HDMI adapter work for my iphone 4.

Being able to get rid of the notification alerts that hinder any functional progress on whatever it is you were doing before the pop-up came along is pretty nice.

Also, the notifications from the lock screen information view is very nice to have. From a usability standpoint being able to triage a sms or email ping sound with one button rather than:

- button click to end sleep,

- swipe to unlock,

- another button click to enter sms or email,

- (maybe) one last button click to open a message.

Multitasking has been available since iOS 4.0. iOS 4.2 was the first version of iOS 4 to support the iPad, though.

MiFi Hotspot sharing app did it for me.

If you have Verizon and are willing to pay for it (I believe it's another $30/month on top of your data plan?) you don't even have to jailbreak. However, I entirely understand if $60 every month is too much; I rooted my Android phone to use it as a hotspot without paying a fee up until I updated my firmware.

Me, too. Being able to tether and not pay extra for it is the only reason I would jailbreak.

actually there are many reasons to jailbreak an iphone not just because of the free apps or the nice tweaks you can get, in some countries getting a legal iphone is really hard (like on my country you have to pay 90$ monthly for a voice plan for a whole year, plus halfs of iphone price) so, unless youre really rich or insane, you need to jailbreak-unlock it to save a lot of money
