Hi! I am long time WordPress Enthusiast, Serial Entrepreneur and Tech Evangelist. I am CEO of weDevs,
Founder of ARCom, Alo Ventures, WPDeveloper.net etc etc. I do read a lot and I write too, I foundered The Tech Journal, The Dhaka Times etc and serving information to millions. I invest and love to help startups and proudly involved with Trance App, Leanplum, FutureStartUp, Geeky Social, Facebook and several other companies from their early stage. Among many other things I was an Early Google Glass Explorer, and I appeared in various (25+) WordCamps around the world. And most importantly I am a blessed Dad of two super cute little princessess, and husband of a lovely wife! And I am from Bangladesh. [More about me]
I have always seen over 3Mbps in my Teletalk(at least in my office and home), and that 3G. 3.5G has the capacity to deliver upto 21Mbps. But whats the point of making it 3.5 or 3.9 or 3.99G when they still provide that lower speed (people reporting they get only 1Mbps in Robi Sheirom 3.5G, in their WIC). And try to think what they will charge for 21Mbps in Bangladesh. Take a guess!
This might happen while you trying to JailBreak then something went wrong, and you end up with a iPhone which had nothing but Apple Logo in it. And you can’t do any thing with it. You can’t turn it off completely or restart or even no response while you connect it to PC/Mac and no response from iTune too.
Here I will explain solution to this problem and details about DFU and Recovery Mode.
In this tutorial I will show you How To Tether An iPhone 3G To any Operation system including Windows XP, Vista, Windows 7, Ubuntu and also Mac OS X and use internet connection. Bangla Version could be found here – BDBlog.Net(Ok, I have dropped BDBlog.net project, find the Bangla version at this TechTunes page.)
Today I suddenly got this trouble. All on a sudden I can’t do any thing with my iPhone. My iPhone is now Firmware 2.2.0 with Baseband version 02.28. Its unlocked and working flawlessly. I just changed the springboard theme image and iPhone becomes non-responsive.
1. Completely black screen. Nothing on the screen at all.
2. Could receive calls.( in the beginning i was able to enable while receiving calls).
3. Nothing happens on touching screen, or pushing home buttons or any other button.
4. I examined and find out i could actually shut down and restart my phone. Though nothing on-screen at all.
5. Works and shows perfect on iTunes. Works perfect in iTunes, you could Sync back or even add any song or any apps via iTunes while connected with pc.
6. Could even charge.
After all main thing is nothing in screen, absolutely nothing. The screen remains dead.
That’s the sweet part. Solution is easy. Just push home button and power button simultaneously for at least 10 seconds. It will reset the phone without harming any data or setting. Now just start the phone as usual with power button. It will show Apple logo a bit longer, but it will start accurately and all problem solved.
BTW if you want to unlock your 2G or 3G iphone with latest available firmware you could use UnlockAlliPhone.com
UnlockAlliPhone.com is the best service you could find online.
