4G Network

Does MetroPcs support Quadband: GSM 850 / 900 / 1800 / 1900 MHZ 2G Network?

Hi all, thanks for your answers in the past.
I am looking into buying a very cool phone on eBay and I am trying to find out if it will work with my MetroPcs account that I currently am using an activated working ZTE C79 phone.
The seller of the phone I want to buy and switch my service to sent me the following answer when I asked him if the phone will work with MetroPcs;
"you could contact your carrier first. If your carrier supports GSM 850/900/1800/1900 frequency, then it could work…This is a GSM mobile phone.(not 3 g or cdma network phone) Please make sure your network is compatible with GSM.."
I HAVE ALREADY CALLED MetroPcs and ASKED THEM this and THEY CANNOT ANSWER this question…..unbelievable…they say only "bring the phone to your nearest corporate store and ask them if the phone can be transfer service to.." RIDICULOUS!
I will NOT BUY NOR POSSES this phonw UNTIL AFTER I find out if it will work with MetroPcs.
Do you know if MetroPcs uses the above mentioned GSM frequency as stated by the seller of the phone I want…. GSM 850/900/1800/1900 frequency? Does metropcs support this frequency?
Note: The phone I want is UNLOCKED.
Thank you in advance if you know the answer…have a good day!
P.S. Please see below you can copy and paste the link to the phone I want on eBay if you want to view it;

When mobile providers upgrade their system from 2G to 3G, is it on the same equipment or do the install new?

Cingular now has 3g network on some phones, what do they do with the former 2g network?

Typically they phase out the older equipment and install new. 2G was very slow in accommodating the data packets that people are starting to use more common place today.

2G uses mostly TDMA or CDMA networks, which originally was an improvement from analog to digital signal, but 3G works better with GSM networks, and GPRS requirements.

Some companies like AT&T/Cingular kept both equipment installed 2G & 3G. But when new towers went in, only 3G/GSM towers were going up. All the TDMA towers were left in place, but eventually people carrying TDMA cell phones, noticed their signal strength was not near what someone else carrying a GSM phone would receive. And then as phones broke down or upgrade new contracts went into effect, the only new equipment you could buy was GSM.
