You can send an e-mail that will send it to the MMS of the other phone. for example I want to send a picture to 123-456-7890. All I have to know is their service provider and a small trick: Say my recipient is an att customer. i just send the email and attachment to firstname.lastname@example.org
. They will receive it as an MMS and you will get them through your e-mail.
As far as battery is concerned you need to know 2 things:
1.) go ahead and FULLY discharge the battery too the point where it tells you that you need to connect it to a power source. This will reset the point where iPhone thinks the battery is at zero
2.) Give it a week of solid use because the Li-Ion battery needs to get broken in a little. Most people, including me, have noticed better battery life after a week or so of use.
Good luck and welcome
