Try this: Low Signal Issue Resolved! - xda-developers I had signal strength around -80, download of .9mb, and upload of .6mb with the previous PRL (59021 or something like that) with the one that's posted I get -60 signal, download of 1.8mb and upload of .9mb. Just follow the steps in the link. If you need to go back just do *228. Make you sure you unzip before you update the prl.
