[Captivate Android Development] devz3r0:
Attached are CWM flashable 2010 & 2011 SGS modems that (for the most part) have the WCDMA 850 band within them. A I9000 based kernel (reoriented) is required for the I9000 modems to be usable on the Captivate, I am not responsible for bricking your phone if you use something else. I did some poking around with a hex editor to compare the files and was able to pull some info out:

It appears that most people are having better success with the "Aries" based modems. If you have trouble with the modems, please make sure your phone is utilizing the WCDMA 850 band and not 1900 by using the instructions below.

From the phone Dial Pad, when you enter: *#0011# you should see one of the following 3G bands:

When testing these modems please only report when connected using "WCDMA 850".

If you are on WCDMA 1900 and want to change to WCDMA 850,

1. From the phone Dial Pad, enter: *#2263#

2. From the "BAND SELECTION" menu select "[2] WCDMA BAND"

3. From the "WCDMA BAND" menu select "[5] WCDMA 850 (FDD V)"

4. Exit out of menu and check to make sure your band is now WCDMA 850 using *#0011#

Note: By default your "BAND SELECTION" is "AUTOMATIC", so if you want to revert your changes, repeat only steps 1 & 2 above, selecting "[1] AUTOMATIC" in step 2.
