Deadfish iPhones send users into deep freeze
When cool isn't cool enough for WiFi
What you need to know about cloud backup
Some iPhone and iPod Touch users who've upgraded to the latest 2.2.1 firmware are reporting problems connecting to WiFi, though in some instances, going outside or sticking the handset in a freezer is providing relief.
Quite what's going on isn't clear, despite numerous suggestions and discussions on the support forums - Apple is being as communicative as ever - but it seems that some users upgrading to version 2.2.1 have found the WiFi functionality failing completely. For some, the updated router software is working, though most users report that cooling down the iPhone provides a temporary respite and some have managed to convince Apple to provide replacement units.
Heat is a significant problem for mobile phones. Faster processors generate more heat, which has to be disposed of somehow. This generally takes place through conduction to the case, which makes heat disposal a big part of device design. The iPhone has two PCBs sandwiched together, making heat even more of a problem, with the proximity of chips meaning that overheating can affect any component, including the WiFi capability.
Of course, with no official word from Apple this is just speculation, and we're not advising anyone experiencing problems to apply an ice pack. Some users have had their iPhones replaced on visiting an Apple Store, so anyone having problems should seek recourse there.
Not that this issue seems very widespread, and if replacements are solving the problem then it's a manufacturing issue, not a design one. The main complaint seems to be Apple's reluctance to be drawn on the problem - failing to respond to queries about the issue and generally treating users as an ongoing source of revenue rather than valued customers that need support when things take a turn for the worst. ®

iPhone v HTC Touch Cruise
I know some of you guys don't always like comparisons, but I run both of the above phones (2 employers/clients) and have had the following experience in the past 4 weeks.
iPhone 3G (2 months old) - after upgrade to latest firmware, WiFi "collapse" and occasional total loss of "sync" with the phone network. The phone was never jailbroken, yet the O2 store where it was bought wriggled and wriggled to the point where they actually told me I was lying. On bringing it up with Apple, they did the same, until I threatened to go to the trade press. Result - new phone. All taking 4 weeks.
HTC (6 months old) - One Monday, camera failed, followed by intermittent WiFi and GPS failure. 10am phoned the HTC Customer Service line, 2pm the phone was collected by UPS. Tuesday 10am - UPS delivered a shiny new phone. Wednesday 10am, HTC technician phoned and gave me a full account of the fault, which he later followed up with an email report. Thursday 10am - UPS delivered an "apologies" goodies kit for the phone.
In my job I am responsible for advising clients on their mobile strategy. Even accounting for the bad press that M$ get for their OS, the advice won't be O2/Apple, also because I want to get the best deal from an operator for my client and not having him tied to one only.
Be my judge guys.
Same Issue Here - No Wifi in iPhone
I am having a similar problem. After 2.2.1 there were higher download and upload speed on my iPhone 2G, and the phone ran hot with wifi radio. Soon after, the phone could not detect wifi, switch between Edge and wifi every 5 seconds, or find wifi networks but list the signals as weak.
Engineers from Apple have contacted me about this problem, but have since stopped after I told them I was having an independent 3rd party complete an analysis.
Took it to Apple store, asked them to replace it because I was in my 13 month with no Apple Care, and they said that it was a hardware problem, but that they would not replace the phone, and suggested I buy a 3G. Way to go Apple.
I left my phone by a window one night, and wifi worked. It was a cold window. Stuck the iPhone in a sealed bag on a paper plate in the freezer for half and hour, and wifi works for a day or two.
Clearly, this is the main issue. If your wifi only works when you freeze the phone, here is what I find to be the only scenarios:
1. You did something to your phone and broke it, somehow only breaking the wifi.
2. Apple designed something wrong and wifi broke.
3. Apple designed something wrong and 2.2.1 caused a set of events that led to wifi breaking.
So, my guess is that Apple is ignoring us because it is like when a car company makes a car that kills X amount of people, and they figure that settling out of court for X amount of people is cheaper than fixing the problem or doing right by their customers.
