Why are my emails from my iphone being sent as attachments?

I call up a contact and select the email address. I type the email and send it. But when it arrives to the person I'm sending it to it is an attachment. When it arrives to the recipient it says my telephone number and YOU HAVE BEEN SENT A PICTURE MESSAGE. How can I make my emails be just that an email and not an attachment.

Is Net10 a good prepaid cell phone plan for iPhone 4?

I have an AT&T iPhone 4. I was going to switch to Straight Talk but then I realized that they don't sell AT&T compatible sim cards anymore. I'm stuck. I'm not going through AT&T anymore and as of right now I don't have service at all on my iPhone. I'm not going to go through the BS of going through another company like Verizon or something, I'm just going to stick with prepaid FOR NOW. So I found Net10 and I heard that it's pretty much the same thing as Straight Talk. Can you give me some details on it? Like it's good enough, what the data limit is, etc etc. Whatever you think is important. Btw, I use my phone a lot but only for texting and calling. I have Wi-Fi at home and when I'm not at home I rarely use 3g.

I got real racing 3 on iPhone 4s
When I did the update for it, it started to load then you do not have enough storage to complete the update. And it wouldnt stop loading! And now I can't play on the app coz it says its loading.

Right now I'm trying to buy the Iphone 4s 16 GB White?

And I just got to the end of the process from at&t, It says
Due Today* $105.99 This is the amount you'll need to pay in full today which can include the cost for a phone, a device, or an accessory, plus the estimated sales taxes for these items. Shipping & Handling, if applicable, will also be included in this amount.

Due Monthly* $112.97 This is a monthly recurring charge that will appear on the monthly billing statements and may not include all existing service charges. Other surcharges, taxes and fees are excluded from this amount.
Added to 1st Bill $36.00 This amount reflects any one-time charges which will be added to your first bill like activation or upgrade fees.

so once I pay for the 1st bill will my bill drop back down to 76.92 or they haven't added the activation fee yet
