Does any know if an unlocked S4 from AT&T will be fully functional on Tmobile's network? What bands are operational on each of the phones?
Real simple answer... GSM works on GSM and CDMA on CDMA. If unlocked it is good for the reason stated or over seas with that countries SIM card.

Here is some info:
T-Mobile GS4 Radios : LTE Bands: 1/2/4/5/7/17 (2100/1900/1700/850/2600/700) MHz; HSPA+/UMTS: 850/1700/1900/2100 MHz; GSM: 850/900/1800/1900 MHz
AT&T GS4 Radios: 4G-LTE Band 4 and 17- 4G HSPA+ with enhanced backhaul - 3G - UMTS 850/1900/2100MHz - GSM/GPRS/EDGE 850/900/1800/1900MHz
I hope this helps.
For example, I purchased the HTC One Developer Edition because T-Mobile showed my area as refarmed to 1900. .... but the area shows as refarmed because they now have 1900 available in my area (Southern California)..
How does this compare with the Verizon version?
Yes, the tmobile s4 will work on lte both with tmo network and at&t network as long as its sim unlocked and has the correct apn. Also, the tmo s4 has an unlocked bootloader (if that is important to you) while the at&t version is locked. The tmobile version is close to being identical to the i9505 (international s4) but with the advantage that it supports lte on at&t and tmobile.So it looks like if I want to switch between ATT & T-mobile and want to experience full 4G LTE capabilities, I should buy the T-mobile version of S4 (M919) and not the ATT version (i337). Is that a correct statement? I am planning to buy an unlocked M919 online and use it with either ATT or T-mobile

Yes, that too. Here is the guide if you are up for it, [GUIDE] Enable AWS on Samsung Galaxy IV AT&T i337 & Canadian i337M - xda-developersThanks. I do not know what does it mean that tmo version has an unlocked bootloader so I may not need it, may be. On internet, I saw that even if I buy i337 (ATT), it can be enabled for AWS and hence can work with Tmo 4g LTE. Does this mean I can buy i337 even if I decide to use it with tmo later? or would I run into any problems? Thank you very much for the help.
