Iphone4: Disable Winterboard Theme using Safe Mode

I just discovered that I can customize themes for my jailbroken iPhone4 using winterboard app. To my excitement, I downloaded themes right away in Cydia. I change one theme to another and it screwed up my phones interface. When I restarted my iPhone, it ask for my passcode. However, the numpad are still screwed up and I can't type the correct passcode to unlock my phone. It disabled my phone twice so I searched the internet for any useful tips to bypass passcode. All the blogs and videos only shows me to reset my iphone and it will wipe out my data ─ and its a hassle for me because I have to jailbreak (with an iOS5) my iphone again!

I tried this video from youtube about steps to bypass iphone's passcode/password without resetting to factory default. 


All I can do with my phone was just play music and when I tap on the icons below, especially on settings, nothing happened. 

Good thing I discovered that I can run my iPhone to a safe mode by opening the dock above (slide finger at the upper part of your iPhone's screen). You can find an option there about power: reboot, power off, safe mode and lock. I selected safe mode and the winterboard theme on my iPhone was disabled and I was able to type my passcode to unlock my phone. Yay!
