iPhone 4 Screen Issues

Today the iPhone 4 was launched in many countries however a few big problems have arisen. The first one being the retina display which on 1000’s of users iPhone 4 is showing a yellow tint in parts of the screen.

However there has been a follow up on this issue someone posting on the AppleInsider forums seems to know why:

Apple is using a bonding agent called Organofunctional Silane Z-6011 to bond the layers of glass. Apparently, Apple (or more likely Foxconn) is shipping these products so quickly that the evaporation process is not complete. However, after one or two days of use, especially with the screen on, will complete the evaporation process and the yellow “blotches” will disappear. How do I know? I was involved in pitching Z-6011 to Apple.
So if this is true then we might see this problem clear within a few days as if not Apple is going to have a huge problem, seeing as in a recent Engadget poll 55% of users said there screen had the yellow colouring issue, which out of a sample of 27,640 people is quite shocking to say the least. This isn’t the only issue of the day that is affecting users but the new revolutionary antenna system seems to be causing big issues with reception and dropped calls, although Apple says it doesn’t it’s just to do with how the signal is displayed.

iOS 4 Custom Firmware (w/iBooks Fix)

Yesterday I provided you with Custom Firmware Restore files for all the iDevices that support the new update and can be jailbroken. This morning the Dev-Team released an update as it had the same issue as redsn0w to cause a problem with iBooks. Obviously if you don’t intend on using iBooks you don’t need to re-download it but I will be re-uploading the firmwares (without custom boot logos) with the fix for iBooks.

Please read this Dev-Team article before using any of the custom restore files.

iPhone 4 To Have 512MB of RAM

Apple are never open about the actual real specs of the iPhone. We know the iPhone 4 uses a A4 chip but we don’t know the clock speed but for Apple to keep up with todays competition it’s been reported that the new iPhone will have 512MB of RAM instead of the 256MB that the iPhone 3GS has. This will give a lot more head room for games, multitasking and other memory hungry apps.

This will also hopefully mean that for the jailbreak community that with the extra CPU speed and double the RAM that WinterBoard and other modifications will run a lot smoother and you can have a lot more complex themes.

iPhone 4 Might Be Able To Playback 1080p Video?

Apple’s official specs on the iPhone 4 state that it can run H.264 video up to 720p at 30 frames per second, Main Profile level 3.1 with AAC-LC audio up to 160Kbps, 48kHz, stereo audio in .m4v, .mp4 and .mov file formats. However if you remember back a few months it was shown that the 3GS could playback 720p/1080i video, although it was not officially supported, see related for the link. So this has made me think that due to the bump in CPU power, now that the iPhone is running Apple’s A4 chip that it should be able to playback full 1080p video.

With the extended battery and retina display, I can imagine that watching HD video on the iPhone 4 will be stunning but I can understand why Apple doesn’t include it official as it does save battery life playing 720p instead of full 1080p.

Also if you plug your iPhone 4 into your TV it would be a useful device to watch HD movies without the need for BluRay.

O2 Imposes 3G Data Limits for iPhone 4 Users

Similar to AT&T in the US, O2 has now put a data limit on pay monthly users. O2 had already put a 750MB limit of Pay As You Go users but have now changed there unlimited plans to have limited data caps. The cost for additional data isn’t that steap and for those who need it shouldn’t be that much of an issue but it opens up a competitive advantage to any of the multiple UK carriers who offer true unlimited data.

iPhone 4 Coming To O2, Orange, T-Mobile, Vodafone And Three in the UK

It began with O2 exclusivity but now most of the major UK carriers sell the iPhone, Three has just been added to that list of carriers which is an intresting move. Three usually offer very good deals and make the devices very cheap so we could possibly see a cheaper iPhone 4 from Three.

All the carries have confirmed that they will be selling the iPhone 4 from June 24th so it’s going to be an interesting launch and a strong amount of competition.

Exams Finished!

So finally after over a month of waiting my exams are over for now, and so I will be returning to blogging and have a lot of exciting stuff planned over the next few months. I will be posting on here as much as possible but also follow me on twitter to keep up to date with whats going on.

Thanks for being patient with me.
