how safe is it to do Paul's guide to changing the T-Mobile Wing PagePool size?

[l1nh]

I am a newbie and my T-Mobile is the same since I got it from T-Mobile and it is so slow

Please let me know how safe is it to do Paul's guide to... changing the T-Mobile Wing PagePool size.
Can I mess up my phone really bad?

Thank you.
