I have a Samsung Infuse 4g Android Smartphone for sale. I changed carriers so I can't use this amazing phone anymore. This is an awesome phone with 4.5" SUPER AMOLED screen, 8 MP camera, hd video, front facing camera, etc... check out http://www.samsung.com/us/mobile/cell-phones/SGH-I997ZKAATT for exact specifications on this phone. This phone is in almost perfect condition in 100% working condition and has always been taken care of. I really wish I didn't have to give this up but AT&T doesn't work well where I live, so I had to cancel their service, pay a termination fee and now I have a great phone I can't use. I removed the SD card to use in my new phone so a new one will need to be put in from your existing phone or a new one can be purchased for $15 from amazon.com or other electronic stores. Includes wall charger and black silicone case. This phone only works on the AT&T network, if you wish to purchase this phone and try to unlock it for other networks that is up to you but it will only work on GSM networks. Please email with any questions. Thanks!
