Yep, you can flash from the internal storage. Just did my first radio upgrade to the Telus radio due to the positive feedback. From sprint OEM to the telus just a quick bar check @ work, on the sprint radio i'd generally hold @ 2 bars and flutuate down to 1 every now and then. With the telus on watching it for the last few minutes I have stayed at 3 pretty solidly, with only a small flutuation between 2 and 4.
