It is now locking up 2 - 3 times a day.. and I have to do a hard reset... Thyis is getting old..
Think I should just take it and exchange it?
If I was at the point of doing hard resets that much the phone would be exchanged. At this point you have very little to walk away from and more to gain by a return.
Did you update to 5.0? If yes to an exchange and don't update no matter how many times it asks you.
I would do the exchange and you get a better phone, now you have a headache to deal with.
