I noticed that iPhones have a very convenient function where 4-number PINs (e.g. 1234, 0000) can unlock the phone without pressing an additional button. On the Pre, if you have set a PIN to unlock the phone, you need to go through the extra step of pressing "Done" afterwards. While it's just one extra button, it adds up over the course of the day especially if you use your phone often but want it locked quickly for security/privacy purposes.
A patch like this would be very helpful to me and the many others who lock their phones with a PIN. Thoughts?
