Blackberry curve 8900 water damaged result no network signal - solution
This blackberry curve 8900 no signal problem is caused by a liquid or water damaged.
This solution can be used or applied only if same things happen also to your blackberry curve 8900. In picture one it shows that a a supply voltage to the RF amplifier is missing or being cut due to a damaged or corroded resistor,
In picture 2, a jumper wire is being applied to sustain the necessary supply voltage to the RF amplifier IC.

Solve Blackberry 8700 series shorted PCB board's battery terminal
This solution can be used or apply to Blackberry series like 8700, 8700c, 8700g, 8700t, 8700v, if found shorted by checking the positive and the negative battery pin terminals
This problem may occurs if the device is being damaged by a liquid or so called water damaged. In blackberry 8700 series there are two power voltage filter capacitor just located near the SIM card socket, this two capacitors will commonly cause the shorted and failed to power up the device. You can try to remove it first then check if multimeter shows no shorted readings (multimeter range to X1 - deflecting of the pointer approximately down to zero ohms in both by reversing both test probes on the battery terminal)
Then replace it with another one same from other blackberry 8700 series handsets.

How to Change iPod Owner’s Name
For my beloved iPod, I have named it Juicy Boxy. However, for this post, I’ve changed it to Jim’s iPod strictly for demonstration purposes. Assume that Jim was the original owner that sold his iPod to Amos. The new owner would therefore, want his name displayed on the iPod (in this instance, Amos’ iPod).
To start things off, you will need to start iTunes with the iPod attached. You will notice that iTunes will display Jim’s iPod; showing the original owner. Using your mouse, highlight the device as shown below
After highlighting the device, wait for a couple of seconds, then click on the device name again (be careful not to click too fast as your computer may interpret it as a double-click). You will now notice that your iPod owner’s name is now in edit mode. Key in the desired name and press the Enter key.
Voila…. You are now officially the proud owner of the iPod. Do this as many times as you want until you found the perfect name for your iPod. In my case, Juicy Boxy.
