I just received an sms with a telephone number on it, but instead the numbers i received only letters.

i have an 1.1.4 iphone with the sms fix installed

how can i fix it?

are you sure this is not an issue of your operator?

is not a operator problem.
Yesterday i installed cydia and the application suggest me to install some files and i accepted, maybe i installed something that i shoudn't

maybe,

Try restoring

Restore then set up a new phone instead of restoring from a backup
