I'm aware of TalkLock and Stormlock for locking your screen while on a call. But is there a similar app. for locking the phone while it's in your pocket, hopefully with an iPhone-style finger-swipe unlock? I'm forever unlocking my phone by accident while it's in my pocket, despite locking it with the "lock" key on top of the device.
I think this would be a FANTASTIC application to be developed. I haven't run across one yet but would really love this lock style feature too. I like Talk lock, but it just doesn't do what I want it to do like what you're saying.
