This type of reception problem has been reported widely in the UK, since the iPhones release on Nov. 9 - see the *UK 02 poor signal strength/reception problems* thread. This may be because the UK markert is somewhat more demanding than the US market, having had better and more consistent mobile technology/reception for some time, and therefore more likely to note when deficiencies occur. Or maybe we are just a bunch of "whingeing poms"...
Recently someone who lives in the UK and has both a US bought iPhone and another UK bought iPhone, has noticed that the US one gets good reception in locations where the UK one gets poor reception. The most significant difference between them seems to be that the US one is running version 1.1.1, and the UK one, 1.1.2. There has been a suggestion that the firmware update was tweaked to give better battery life performance, at the possible expense of signal strength, perhaps by not boosting the signal as much in fringe or marginal reception areas.
As a variety of reports have been posted on this thread, some positive and some negative, it would be interesting to know whether those who experience no significant reception problems are running 1.1.1, and similarly, whether those who are having problems are running 1.1.2? In relation, whether anyone who has upgraded to 1.1.2 has better battery life than before?
For what it's worth, I had 3 phones side by side last night - a Nokia, a Sony Ericsson and an iPhone (1.1.2), all on the same carrier (02, broadcasting in the 900 MHz frequency band). Both the Nokia and SE gave 4-5 bars, whilst the iPhone sometimes gave 2-3 bars, but more often 1 bar, with intermittent loss of signal altogether. Clearly, the iPhone antenna is not as sensitive as the other phone's antennas, and is in dire need of signal boosting in some locations. Just for the record, the phones were not being held, therefore the antennas were not covered by my hand, which is another area where the iPhone signal reception suffers more than other handsets.
