Well i upgraded to .122..... I am on tmobile and have a 9530 running OS .122 and I'm loving it~! I always had issues with the .113 especially EDGE issues. This upgrade has helped that bug so much! I have been on EDGE for 2 days already! and the browser is fast!!! i love it! My APN: emgsm.vzw3g.com... to upgrade go here:
Yup, i'm using the same firm with same carrier, T-mo.
I'm happy to report that it holds EDGE very well most of the time but will drop to edge sometimes. I think this is location dependent though, becuase it holds very well at my school but doesn't do so well at my apartment sometimes. overall very good firmware!
