I even bought the Vodafone Sure Signal Booster and it still happens. I do really like the iPhone but the problem is definitely worse when using it towards a Nokia etc..
Power bar is full, use it in the centre of Dublin and travelling. I presume it's a Vodafone network issue, they mentioned an iPhone 4/Dublin issue. Never experienced such an unreliable phone.
I just got one last week on the 3 network. Living in a large town, you'd would think signal would be no problem. Love all the features of the iphone but the signal is never anymore than 3 bars, it regularly flicks to no service and i have to resend texts and drops calls. Thinkin about goin back and asking to switch back to meteor and try them on the iphone.
I've had the iPhone 4 since last September with 02. I've never had any issue with dropped calls or poor signals, other than in areas where there is known to be a poor signal.
Not sure if problems are related to particular networks maybe.......
It's such a well publicised issue I'm surprised that people are still asking. [broken link removed] Effectively one of the dangers of adopting early or the marketing hype that moves a device before the right time. So many tech companies are guilty of this. I guess you could call the iPhone 4 the Alfa of phones; people love them but expect the unexpected.
