** MEHTOD REQUIRES ROOT ** <-- Accessing and changing files in "/system/app" requires Root access. Alright well, I just thought it would be useful to have this somewhere in the MetroPCS forum. Why am I posting here? Because this applies to all Android phones whether they are from MetroPCS or not. For those who have a MetroPCS Android phone, it is safe to delete the "Mms.apk" file from "/System/app". This is the stock Messaging app that comes with all devices. HOWEVER, it is never a bad idea to have a BACKUP of said app just in case. You can never be too careful. Anyways, BEFORE you delete/move the "Mms.apk", you want to download any messaging app from the market, say.. GO SMS which is the one I use. ~* Instructions for GO SMS *~ 1.) Open the app and click the menu button on your device to bring up the menu options. 2.) Tap on "Settings" and select the "Advanced" tab. Scroll all the way down and tap on "Important Tips". Check the "Stock SMS Uninstalled?" option. 3.) Go back to the previous menu and now tap on "MMS Settings". Scroll all the way down and check the "Fill APN Configuration Manually". Then insert the following information: MMSC: http://mms.metropcs.net/mmsc MMS Proxy: wap.metropcs.net MMS Port: 3128 4.) Delete/Move stock "Mms.apk" from "/system/app". 5.) Enjoy sending MMS through a better & customizable app. NOTE: To send a regular MMS message from GO SMS, create a standard text message, tap on the paper clip at the left of the input field, then tap on the fifth icon. Finally, select whatever is that you want to send. It should work just fine. ** Credit ** The actual MMS settings used in this post were taken from the following thread in a different forum: http://forum.ppcgeeks.com/htc-vogue...-web-mms-setting-metro-pcs-please-sticky.html All credit goes to DumbDumb from PPCGeeks.
