33. accept the terms and follow the instructions... (it will ask you to put your phone in recover mode by turning off your phone and pressing the back button while plugging in your phone via usb) you can make this process quicker by simply already having your phone plugged in and simply pressing and holding the top power button+back button+home button until the green light remains on.

34. the program will tell you that there is new software available for your phone

35. install and enjoy 2.5

Extras step to making the experience even better!

i personally don't like the boot animation of the new 2.1 update and would rather not have the claro operator logo at the boot startup. the way to do that is:

root your phone again by following my instructions earlier, and install the root explorer.apk file again from your sd card. once your have root explorer installed and working navigate to SYSTEM and then to MEDIA. in media you will see a bootanimation.zip file, simply delete it.

Now for removing bloatware (operator specific applications):

to remove application that may be of annoyance, just go into root explorer again and navigate to SYSTEM and the to APP and dele and .apk files that are programs like ei: claro.apk... make sure you press the r/w button whenever you want to delete or overwrite something in SYSTEM. And be aware that if you don't know what your doing, you can brick your phone. SO BE CAREFUL!

And finally, as most would already know, this is all at your own risk. Sometimes its better to leave these types of hacks alone if you don't know what your doing.

I take no responsibility or credit for any of these hacks. thanks to all the members on XDA Developers for your support and help.
