I wonder if anyone had experienced my iPhone 4 problem:
The second day i purchased my ip4, i went to The Garden's Club lounge with my friend and online there (WiFi) for half day without problem. Few days back, I went there again but the WiFi was unable to connect. My friend's N8, his laptop, my laptop all can connect without a problem, only my ip4 having issue. Once I start the connection, it immediately failed and stated "Unable to connect to xxxxx", don't even see its trying to connect. Even resetting the network in ip4 didn't help. I surfed the net for this issue, and finds that WiFi on ip4 is not compatible with a numbers of brand of router/modem. Wonder what problem is this.

After leaving the lounge, i tried to online at starbucks, mcd, all without problem.

Kindly read the pinned threads and please do a search before you post.

well most of the info is applicable for ip4
if purchase from local telco (maxis, digi), it's official unlocked
if purchase from online apple store, it's official unlocked
if the ip4 came from US (AT&T set), it's official locked...
And check whether the "Carrier" item exists in the setting... If not, it's software unlocked...
something like this...

i don't see any problem on your screen?

Yes, you can't. iPhone warranty can only claim from the country you purchase it.

not sure about the call failed and call ended problem.
for the signal, do you actually hold the ip4 "incorrectly"? do you touch the death grip?
and if i'm not mistaken digi 3g speed is on average of 700kbps where 0.3~0.5 should be normal? correct me if i'm wrong...

yup is the left-handed gap. for my ip no problem wor, although when i hold the grip the signal will lose, but it dont really affect me much...
if you have a case then i think it shouldn't be the source of problem. maybe your area digi coverage not good? because for certain areas digi coverage is bad.

Been facing a problem for few times, suspect is a bug in iOS 4.1?

After voice call ended, sometimes the screen just goes totally black, left with only the top status bar (carrier, time, battery, etc), as attached picture. Pressing Home button will bring out the querty keyboard but typing doesn't have any effect. Solution to get it back to normal is to press the power button, lock the phone then unlock it.



Anyone also having this issue?
BTW I'm using iPhone 4 32GB loaded with iOS 4.1. Jailbroken. But I don't think is JB causing problem, because before JB also having this issue.

No need. Google li-ion battery for more info.

Dude, you don't understand me? I was not saying it must not caused by JB, what I was saying was it might not be JB causing the problem, because before i JB it, such problem also exists. I even had reset the firmware before, but this problem also exists in random. And I believe I'm not the only one faced this problem before.
