if you have rooted with revolutionary,you have the unique option to simply recieve the ota,after replaceing your recovery with the stock one. the revolutionary hboot will not disapear after the update,and it will allow you to easily reroot.
biggest advantage of doing this is that it will not wipe your data or require you to re-setup your phone.
check your firmware in settings/about phone.
if you have 1.70.605.0,then use this recovery:
MR2:
Multiupload.com - upload your files to multiple file hosting sites!
md5: [COLOR="red"]a3320797390e3d746a67fda915854b16[/COLOR]
if you have 2.11.605.3 then use this recovery:
GB 2.11.605.3:
Multiupload.com - upload your files to multiple file hosting sites!
md5: [COLOR="Red"]a3f6155023f3c928d0cd229516a441e1[/COLOR]
download,rename PG05IMG and flash in hboot,as you would a radio or any other recovery.

MAKE SURE to double check your MD5 sums to verify the integrity

MAKE SURE you are on one of those 2 firmwares. if youre on something else,i cannot gaurantee that mixing the recovery with a different firmware is acceptable and will not cause issue.
