Hello, I updated my 8310 from 4.2 to 4.6 without removing the sim or memory card. I'm sure you can do the same. 8310 is at&t and 8320 I assume is tmobile, but should apply the same. I hope this help.
You dont have to remove them but some do just in case. I personally dont. Also just thought you might like to read the link in my signature for proper upgrade/downgrade procedure for detailed instructions on your upgrade. Hers the link just in case. http://forums.crackberry.com/f95/pro...ocedure-53359/

How did you get 4.6 for an 8310? How is that possible?
