For the last 2-3 months, the data being used by my iPhone is excessive and I can't understand why. Here's what my bill says: May 14 - 40MB May 18 - 20MB May 20 - 11MB May 23 - 10MB May 24 - 90MB May 28 - 50MB May 30 - 113MB June 3 - 30MB June 4 - 35MB June 6 - 42MB June 9 - 30MB June 11 - 22MB June 12 - 17MB Here's my usual usage: -I NEVER stream any video. -I receive emails on it, but rarely reply (maybe reply to 1 email per 2 days). -I use the Twitter app for about 30 minutes a day just reading -Sometimes use Maps. Maybe 5 minutes a day. -Text messages. Rarely MMS. Does anyone have any ideas? I have a 500MB plan and it should be enough. All this data has me very confused.
