Timestamp column in iOS SQLite database

Sun, 14 Apr 2013 15:59:45 +0000

I was researching a database from an iOS app called <appname>.sqlite. From the filename it was obvious that we were dealing with an SQLite database.

I opened the database with SQLite Database Browser and the table I looked at has datetime values which are expressed in the TIMESTAMP data format in SQLite:

SQLite documentation indicates that the TIMESTAMP format is based on unix time: the number of seconds elapsed since 01-01-1970 in UTC time.

From Jailbreak to Jailbreak part 2

In this post, which is a followup on my From JailBreak to Jailbreak post, I will describe the same procedure for A5 devices (iPhone 4S and iPad 2).

A lot of the stuff is really the same so I will not describe that again, this includes the actual update to iOs 5.01, xBackup, SHSH signatures and backup using iTunes.

Currently the Jailbreak for A5 devices with iOS 5 is only for iOS 5.01. Since Apple is expected to release iOS 5.1 very soon it’s highly recommended to update to iOS 5.01 NOW. Especially because it’s not yet possible to downgrade to iOS 5.01 using Tiny Umbrella.

From Jailbreak to Jailbreak

A few days ago I decided to update my iPhone which was still running iOS 4.3.1 to iOS 5.0.1. I delayed this update for a while because I had Jailbreaked my iPhone. Unfortunately an update is much more work when you have Jailbreaked because you also have to restore Cydia settings such as the repositories and Cydia installed Apps.

This blog post is not a guide on how to Jailbreak but more a collections of tips to go from a Jailbreak iOS 4.x to iOS 5.01.

If you notice any extra steps while doing your update please send them to me so I can add them to this post.
