The network gridlock that Apple suffered when it launched the iPhone 3G last Friday was a result of being unprepared and could have been avoided . but there are still inevitable iphone complaints :

1) The 3G Network:

Suspiciously poor 3G reception and speeds. Specifically, we’ve seen several people report one bar of 3G reception in areas where other devices report strong reception.This may be a problem with a batch of iPhones, or with something in AT&T’s network, though we’ve also seen someone reporting the problem on O2 in the UK.

“- it would mysteriously drop from four bars of 3G to one for no apparent reason, while our Motorola RAZR2 V9 reported better reception . Then it would shoot back up to four bars for no apparent reason a few minutes later.”

2) Incompatibility with accessories:

Buyers of Apple’s new iPhone 3G are complaining that, unlike the original version, the device can’t be used with many of the pricey charging stations, sound docks, and other accessories they had bought previously for their iPods.

A number of forum members speculated that the problem relates to the fact the iPhone 3G exclusively uses a USB connection to link to charging devices, whereas the original iPhone can use either USB or Firewire connections.

3)Web Browsing :

Some are complaining that the Safari Web browser is prone to crashing on the new devices; others said they couldn’t get the iPhone 3G’s vaunted GPS feature to work properly.

4) Battery life :

According to users iPhone 3G delivered 4 hours, 27 minutes of talk time. Also found the battery indicator on the new 3G model slipping below 20% by early afternoon or midafternoon on some days, and it entirely ran out of juice on one day. Added that the iphone turned down the screen brightness, and at times turned 3G off entirely to save battery.

5) Cost:

Reviewers point out that despite a drop in the cost of the iPhone itself, having one will end up costing you more than owning a first-gen iPhone. That’s a result of increases in the cost of AT&T’s phone and data plans. Though you save $200 on the phone, you’ll pay $240 more for the service over the life of the two-year contract you must purchase,

6) GPS:

They can’t provide turn-by-turn directions, merely showing you as a blue spot moving along a map–and sometimes they can’t even do that.
