We mentioned the other day that Sprint was aware of user-reported issues with the Epic 4G, particularly with slow 3G upload speeds, and that an update was incoming today. As promised, Sprint has delivered, and we have the details for you from the official Sprint support forums:

Fixes:
WiFi standby battery drain
Amazon MP3 cannot download in 4G
Large emails lag in upload speeds
Increased 3G upload speeds

Update your software
1. The software will be automatically downloaded to your phone since this is a recommended update.
2. A System update screen will prompt the user to ‘Install now’ or ‘Install later’.
If ‘Install later’ is selected, a reminder will be sent once or twice a day to install the update.
If ‘Install now’ is selected, the phone will power down and then reboot.

Important Notes:
- This update will take approximately 7-8 minutes to download and 7-8 minutes to install.
- The new software version is: S:D700.0.5S.DI18
- This update is available OTA (over the air) and will be pushed to your device.  It is being pushed in stages, beginning on 9/30 12:00AM EST, and will be rolled out to users over several days.
- Your device must be on software version DI07 to perform the update to DI18.  If you are still on DG17 or DG27, a Sprint Service and Repair Center should be able to update your device to DI07.  The update from DI07 to DI18 is not yet available to the Service and Repair Centers.  As soon as it is, this post will be updated.

If you own an Epic 4G and have been experiencing slow 3G upload speeds, leave us a comment below and let us know how this update works out for you.
