By default, screen Auto-Lock is set to one minute on your iPhone and 5 minutes for iPad.  Make sure you know what you are doing if you choose the “Never” option.

It is not recommended to turn Push off if you use iCloud for mail, contacts or calendars and require up-to-date data to be always available.

As pointed out by German site iPhone-Ticker.de, German mobile carrier Vodafone is now listing iPhone 4 (8GB) Black & White and iPhone 4S (16GB, 32GB, 64GB) Black & White under the compatibility device listing for an iPhone 4 bumper. This seems to line up with the running rumor that there will be a low end iPhone 4 8GB model together with brand new next generation iPhone. Coming from Apple’s partner, this appears to be what we will see unveiling in about 30 hours in Apple’s October 4 event.

After 18 months of waiting, many fans definitely will be disappointed and underwhelmed by a simply beefed up iPhone 4. Many have expected a brand new design with a bigger screen for next generation iPhone. This does not sound like a good debut for new CEO Tim Cook.

There are lots of apps for messaging on the iPhone. But WhatsApp Messenger appears to be leading the pack with its simple approach to chat and messaging. There are lots of advantage of being simple: an interface that mimics that of iPhone’s Messages app; there is no login requirement to a chat network; no need to add in contacts as the app uses your existing contacts’ phone numbers. WhatsApp is essentially online chat dressed in a SMS suit, except you do not have to pay for the SMS charges, even for international chat. And the app is available for Android, BlackBerry and Nokia phones as well.

Finally, the October 4 date is confirmed. Apple today sent out invitations for a special event titled “Let’s talk iPhone”. Venue is at Apple’s Cupertino headquarter Town Hall auditorium and the event will begin 10:00 AM Pacific Time.

Apple is expected to roll out new iPhone hardware. It is still a wild guess if we will see an improved iPhone 4S, a brand new design iPhone 5 or both. iOS 5, iCloud and new iPods are also expected during this event.
