Past few weeks both my brother and I have noticed a sporadic speed reduction in our iPhones from just browsing the web with safari to other web dependent apps. At first I was thinking I went over "unlimited" cap but my brother had a tiered data plan but he's in the same boat. Next I figured the area we are in but my HTC Titan and his Inspire both run through the web just fine. Anyone else we talked to with android/wps have had no issues. Surely we both didn't get faulty units? He purchased his 4S in November and I purchased mine in March. Anyone else having problems?
