iPro E71, bluetooth and change font size and colour

[nelvex]

Dear Sir,
I bought an iPro E71 phone and work good but when I want connect to computer via bluetooth connection the computer found the phone with device address 3b:2a:... but not with your name iPro and the bluetooth software from computer say "no services" so i can't send and receive files between two device, phone and computer. When i make bluetooth connection with another phone like Sony Ericsson I can send and receive file between two device.
Another question is: can I change the text color from my phone because cannot good see the text (text is white and the background is yellow) or can I change font size because the letter are too small and I cannot see very wheel the text (number, name, etc.). The software has following version K33L-P2-R1-NOTV-C2-SA1-F3-2-VO3.
Thank you.
