Me and My friend both owned a T - Mobile and it has very good features with many advantages , this internet smart phone has excellent quality with best features . it is available in Black , Red and green in color . light weight with strong battery will add a additional plus point to it .the major effective disadvantage which i found in this smart phone is just software problems it has a strong Android Operating System with it but though some times some files cannot excess in time and that makes me so irritative .

# Display :
It has high resolution TFT - LCD Screen with 480 X 320 pixel resolution . this quite stylish touchscreen makes work more reliable and easy in all the manners , this smart phone has half sized VGA screen which will give you a better clarity and the best performance . it has good touch screen , normally I phone , I pod or Apple Inc has this kind of amazing screen .
# Keyboard :
This mobile phone contains a keyboard as well (This phone is equal to a personal computer / laptop) . T - Mobile smart phone keyboard called QWERTY (Straight Row of letter's) . it comes with set of SIX navigation buttons : Phone , Home , Trackball , Back , Menu , A touchscreen all are normally navigation of this qwerty keyboard . This sliding qwerty keyboard is very easy to use and very comfortable like normal personal keyboards .

# Camera :
Good effective and strong Camera you will have with this T - Smart phone . this G1 has 3.2 mega pixel camera with 3GPP Faciltiy , i found a normal disadvantage is this camera doesn't have flash light as a result very poor in low light or in dark nights . MPEG4 you will have with this T - Mobile G1 .
# Battery :
The battery is really very good and a strong one . just charge once and no need to worry about around 2 days . it provides 4 hours of talk time and normally 125 hours of stand by facility .

# Audio :
If you are a music lover then i am sure you will love this phone because it has a brilliant , amazing clarity which you can feel and the main advantage -- Each and every file support is there with this T - Mobile , The G1 supports audio files in MP3, AAC, AAC+, WMA, MPEG4, WAV, MIDI, Real Audio, and Ogg formats .
# Storage Capacity :
Before buying this phone i thought it may have unlimited capacity to store but i was quite disappointed but though this capacity is also more than enough , Micro Sd Card should be inserted in this mobile and you will get 1GB micro sd card with the set , The main and major thing is that you can extend up to 16Gb (which currently not available in india) .

Conclusion :
I love this phone because of it's amazing and good features , apart from this The T - Mobile G1 has many features which a normal standard phone have . Operating system Android 1.0 is fantastic . i tried to download mini opera from my samsung j 600 but it wasn't possible but in this phone it doesn't got any problem to download it . i am using Chrome (Google Browser) with it
