MetroPCS PSA: Look to see if your phone's affected

Look and see if your phone will be affected by this

This morning, UPS delivered a letter from Metro. I imagine these are being sent to all the area stores/dealers:
"Due to the LTE network integration between MetroPCS and T-Mobile some phone models may experience an incompatibility issue that causes them to lose 4G LTE data connectivity. These phones will need a free software update in order to maintain optimum performance."

"Customers who do not have the latest software version may experience loss of 4G LTE data after July 31st, 2013."

Inside was a microSD card for installing onto phones that can't be updated via OTA.

I immediately updated the store's demo phone, which had been experiencing intermittent connectivity issues for several days which, of course, was taking a toll on the battery, as well as making the phone feel hot.

Since then, data connectivity has been consistent, the phone doesn't feel hot, and the battery isn't draining so quickly.

If you have a Coolpad Quattro, Huawei Activa, LG Connect, LG Esteem, Samsung Craft, Samsung Galaxy Indulge, Samsung Galaxy Attain, or Samsung Galaxy S Lightray, your phone may be affected and may need to be updated.

Correct.
