Other mistake: Michael goes to Fox River in April. Maricruz gets pregnant in the same month. In mid-June, when Michael get arrested in Panama, she's still pregnant. That's 2 months. He was in there for about 2 weeks, due to his deal with the company. Therefore, he would have escaped Sona at the end of June or the start of July. The start of Season 4 is set 3 weeks after the escape from Sona, so Maricruz should be 3 months pregnant, but gives birth at the start of season 4, meaning that the baby is 6 months early but looks very healthy.
Other mistake: The psychologist shows Michael a photo of his family with his Mom, Dad, Michael and Lincoln but Michael never actually met his father when he was young.
Other mistake: While Paul Kellerman talks to Lincoln about Sofia and LJ, Dominic Purcell has a tattoo on his left forearm saying "j.c. 1950-2008", which should have been hidden as season 4 is set in 2005. (00:40:57)
Other mistake: Sarah and Michael are walking along the beach at the end. There is quite a clear path disturbed in front of them from where they practiced the shot before.
Answer: Roughly as follows. Linc "kills" Steadman in 2001. Michael robs the bank on March 9th 2005 and is sent to Fox River on April 11th. The breakout from Fox River takes place on or around May 25-31. Michael arrives in Sona on June 17th 2005. More details are here: https://prisonbreak.fandom.com/wiki/Prison_Break_timeline.

That wouldn't make sense because the original grave stone in series 4 has Michael's death date as 2005, which is supposed to be at least 3 years after Fox River.
