The Apple iPhone 3GS did indeed get an upgrade in downloading speeds which now supports 7.2Mbps which is all good, so this means the downstream is good but what about the upstream?
RapidRepair ripped the iPhone 3GS apart and found a Universal Mobile Telecommunications System High-Speed Downlink Packet Access (UMTS HSDPA) chip which apparently is one of the older 3G chips which will support maximum upload speeds of only 384kbps.
We would love to know if you are having problems with upload speeds being limited to 384kbps, we want the iPhone 3GS to upload videos faster than laptops with 3G cards which will be a very good indeed to say the least.
Many users or the iPhone 3GS has reported overheating problems, battery life is not as good as they thought it would be and now the 384 Kbps upstream being poor, how many more problems will people find? To tell the truth we have not found any problems with this smartphone as of yet. We will be bringing you a hands-on review pretty soon.
