Many times the 3G service indicator will simply disappear in the middle of loading data - whether it be through the browser, Maps, Android Market, etc. When the indicator goes away, a message box appears saying that there has been a network error. Once in a while, the 3G will come back for a few minutes, but it always cuts out again. This has been happening for about 42 hours and it is highly aggrevating to say the least. Also, I should mention that a "soft" wipe through calling *228 did not change anything. I have completed about 20 reboots.
